Who is the antagonist in All my Sons?

Answer 1

Kate Keller is the antagonist. It is for her, as the vanguard of "family," that Joe commits his crime and creates his excuses. She presents the most obstacles. Of course, I think that Chris is the protagonist of the play. What Joe has done has been done, it is Chris's story. In this view, it is easier to see Kate as the protagonist as well. Here's how it works:

What does Chris want? Anne, and closure, and acceptance from his mother about Larry's death. Deep inside, he also wants the "truth" about the airplane parts, but that doesn't come up until the end of the play. Kate refuses to accept Larry's death, and she doesn't want him to marry Anne. Therefore, she is the antagonist.

That is one view.

Another view is that Joe Keller is the protagonist. He is a an outgoing, kind and working man trying to life his life in peace. This is primarily about Joe, not Chris. The primary antagonist is Ann Deever, while her brother George Deever being the secondary antagonist. Even though she might not intend to bring harm, she is the one bringing destruction on the Keller family and Joe's peace, when disclosing the suicide letter from Larry. Chris might even be seen on as an antagonist in that he wants to marry Ann.

Answer 2

The antagonist in "All My Sons" by Arthur Miller is Joe Keller, the main character who is responsible for selling faulty airplane parts during the war, resulting in the deaths of twenty-one pilots. He struggles with guilt and denial throughout the play, ultimately facing consequences for his actions.
